How to properly install Ubuntu on LVM?

Question

linux

I install Ubuntu server-on the hypervisor, added two virtual hard disks for ubuntu server, on the first disk I create (without LVM) a partition for /boot and then I make this disk a boot disk, then on the same disk the remaining free space I create an unformatted partition
Then I create LVM -group but, the problem is that the system only sees the second disk, does not see the first disk that I created an unformatted partition
Please help

Answer 1

before doing LVG, you need to determine the PV (physical volume)
pvcreate / dev / sda2 (for example, which one you have unformatted on the first disk)
